I would like to see a grid lines system on the UI like RIFT had back in the day, helps make sure you "Center" things when you're trying to move around Windows. Could even add the ability to anchor things to a specific spot in the grid, and it would "hopefully" maintain the anchor through resolution changes

Yeah, it would be very cool if it remembered the positions on diff screen sizes. I change all the time, full screen, max windowed size, and even 800x600 when harvesting. Moving the UI around constantly each time I switch is very, very annoying
